And don't forget New Glenn uses Methane which solves the coking problem for reusability. Coke buildup plagues Falcon more than people realize.

I think some Falcon 9 lower stages have already been reused 30 times, which suggests coking is not a major problem.

The individual Falcon turn-around is slow (months of refurb), and the record half-month ones swapped some engines. B1067's 30-reuse is a ship of Theseus rebuilt over 4+ years.
